That is, the coin mock 20 is a mechanism that controls the counting of coins, the sending of a sales permission signal, the payout of change, etc. according to the input of coins, and the setting of the product selling price at the coin meck 2 rivers is performed, for example, by applying 1-2 to its output. The comparison circuit 24 compares the price set by the switch 21 with the input amount sent from the currency counting mechanism 23, and the input amount is The product is configured to issue a sales permission signal when the product sales price is equal to or higher than a set product sales price. In the coin mech 201 for multiple price sales, the product sales price setting switches 21 are installed according to the number of set prices, and therefore the sales permission signal output terminal provided on the coin mech 20 also serves as the product sales price setting switch. 21. The output terminal of the sales permission signal provided in the coin pick 201 is connected in the relay box 30 to a product sales circuit 41 provided for each column of the vending machine main body 40 by a price selection switch 31. A price selection switch 31 provided in this relay box 30 configures, for example, a matrix circuit from an output terminal for a sales permission signal of the coin mark 20 and an input terminal for a sales permission signal of a product sales circuit 41, and sets prices in rows and columns. is configured to short-circuit according to the selection of the terminal. Therefore, the price selection switch 31 selects the price of the product in each column. Furthermore, the vending machine body 4
Each price plate is provided on the display section 43 near the product selection switch 42 of No. 0 to inform the customer of the selling price of the product. 31, one with a predetermined price is selected. The price setting for conventional vending machines as described above is based on Coinmetsu 20.
, the relay box 30, and the vending machine main body 40. Therefore, if even one of them is incorrect, the settings will be incorrect.

Furthermore, when setting a price, it is necessary to know the correspondence between the price setting switch 21 in the coin mech 20, the price selection switch 31 in the rapox 30, and the price display part 43 in the vending machine main body 40'. The problem was that it was complicated and that it was difficult to confirm the settings at a glance. SUMMARY OF THE INVENTION In view of the above-mentioned points, an object of the present invention is to provide a vending machine that makes it easy to set or change the selling price of a product and prevents fraudulent setting. The configuration will be explained in detail below based on the block diagrams shown in FIGS. 2 and 3.

FIG. 2 is a block diagram showing a schematic configuration of an embodiment of a vending machine according to the present invention, and parts that are the same as or correspond to those shown in FIG. 1 are given the same reference numerals.

In FIG. 2, normal sales are carried out in the sales circuit 41 based on the sales permission signal from the comparator circuit 24 and the selection signal from the product selection switch 42, as in the past, but in order to set the sales price, Setting circuit 5 as shown in the figure
0 are provided corresponding to each product selection switch 42, or are provided so as to share a portion thereof. This setting circuit counts the number of selection signals generated by operating the product selection switch 42 in a predetermined operation mode (setting mode), and sends a signal corresponding to this counted value to the comparison circuit 24 and the price display section 43 having a display. Configured to send as a set price. That is, according to the present invention, the product selection switch 42 is used for price setting, and the set price is input to the comparison circuit 24 and the set price is displayed on the price display section 43 only by operating the product selection switch 42. I have to. Specifically, the device using the product selection switch 42 for price setting as shown in FIG. 2 can be implemented by the device shown in the block diagram of FIG. 3.

In FIG. 3, reference numeral 42 indicates the same product selection switch as shown in FIGS. 1 and 2. Reference numeral 2 designates a price setting circuit which, when a selection signal is applied by operating the product selection switch 42 while a setting mode input is being applied, counts the number of selection signals caused by the operation of the product selection switch 42, and calculates the selection signal by operating the product selection switch 42. An output signal corresponding to the count value of the signal is generated from the terminal A, and the count value of the counted selection signal is erased when a reset mode input is applied.

Therefore, if one operation of the product selection switch 42 corresponds to one selection signal, for example, when setting a price of 10 and q, one sub-operation of the product selection switch 42 will change the set price. A count value corresponding to lowq is obtained, and an output signal corresponding to this count value is generated from terminal A. Reference numeral 3 denotes a price reading circuit, which is configured to receive the output signal from the terminal A of the price setting circuit 2 and to store this world power signal, that is, the set price.

The set price stored in the price input circuit 3 is sent to a price display unit 43 provided near the product selection switch 42 so that the customer can check it, and is displayed on the comparison circuit 2.
It will also be sent to 4. In addition to the set price signal from the price logic circuit 3, the comparison circuit 24 receives a signal corresponding to the input amount from the money calculation control section 5 as an input, and compares both signals to determine whether they match or not. It is configured to generate an output signal when the signal corresponding to the input amount becomes larger than the set price signal. Reference numeral 5 denotes a money calculation control unit, which includes a coin sensor 11 that identifies the inserted coin and generates a pulse according to the amount of the coin, and a change sensor 12 that identifies the dispensed change and generates a pulse according to the metal of the coin. and a change dispensing mechanism 13 for dispensing change, and are configured to calculate the input amount and the amount of change. Reference numeral 6 denotes a sales permission signal generation circuit, which is configured to form and send out a sales permission signal when the above-mentioned output signal from the comparison circuit 24 is applied.

Reference numeral 7 denotes a matching circuit, which transmits a sales signal to the sales mechanism drive circuit 9 and money calculation control when the sales permission signal from the sales permission signal generation circuit 6 and the selection signal from the product selection switch 42 match, that is, when they exist at the same time. 5.

Incidentally, a product selection switch 42 added to this matching circuit 7
The selection signal from is configured to be applied via the selection circuit 8. Based on the output signal of the inverting circuit 14, this selection circuit 8 sends a selection signal from the product selection switch 42 to the coincidence circuit 7 only when there is no setting mode input, and operates the product selection switch for price setting. is configured to lock the selection signal. The price setting operation of the enchantment having such a configuration is as follows.

First, a setting mode input is applied to enable the price setting circuit 2, and the number of selection signals generated by operating the product selection switch 42 is counted and stored.

Here, if it is decided that 10 yen will be set per one operation of the product selection switch 42 as described above, if the selling price is 100 yen, the setting can be made by pressing 10 times, and the price will be stored in the price setting circuit 2. Sales price data and price logic circuit 3
is entered and stored. In addition, this stored content is sent to the price display section 43 and displayed, and is also sent to the comparison circuit 24.
It is also sent to The price setting operation ends when the setting mode input is no longer input, and the selling (setting) price stored in the price reading circuit 3 does not change even if the product selection switch 42 is operated thereafter. After the setting operation is completed, the customer inserts coins and the inserted amount is counted by the money calculation control unit 5. As described above, the comparison circuit 24 compares the inserted amount with the set price, and the inserted amount is determined as the set price. , a sales permission signal is issued via the sales signal generation circuit 6, and the matching circuit 7 compares this sales permission signal with the selection signal from the selection circuit 8. A sales signal is generated to activate the sales mechanism drive circuit 9 to perform a sales operation.

The money calculation control section 5 receives the sales signal from the coincidence circuit 7.
For example, the set price stored in the price input circuit 3 is subtracted from the input amount to calculate the amount of change, and the change is paid out according to the amount of change. If an incorrect setting is made during the price setting operation, a reset mode input may be applied to the price setting circuit 2 to erase the stored contents, and then the setting may be made again. In the embodiments shown in FIGS. 2 and 3, the money calculation control section 5 and the coin sensor 11
, the change sensor 12, and the change dispensing mechanism 13 are of course provided in common, and the price setting circuit 2 may also be provided in common depending on the case.

In this case, a logic circuit or the like may be configured so that the count value of the price setting circuit 2 is read into the corresponding price logic circuit 3 in accordance with the selection of the product selection switch 42. According to the present invention as described above, a value corresponding to the number of times the product selection switch is operated in the setting mode is set and stored as the sales price corresponding to the operated product selection switch, and this stored sales price is used when selecting the product. In response to the switch, the price is displayed directly in the price display section where customers can check it, so simply by entering the setting mode and operating the product selection switch, the selling price can be changed and the price displayed. The display of the section is also changed, so there is no mistake in the correspondence between the selling price set on the product selection switch and the selling price displayed on the price display section, and the setting of the selling price can be easily changed.
